example 1
[0019] Example 1: Attached figure 1 The shown internal return UASB unit-cone group facilitates sludge granulation.
[0020] In the internal backflow UASB, three sets of cone sets 3 consisting of three cone buckets are installed at different heights by using the cone set holder 2 . During the operation of the internal reflux UASB, the water enters from the conical bottom water inlet 1, the sludge particles at the bottom of the reactor expand, and the utilization rate of the granular sludge increases. There are a large amount of small floc sludge and free microorganisms in the middle and upper part of the suspended sludge area at the lower part of the three-phase separator 4, and a reflux liquid extraction point 8 is set here, and the flow rate of the reflux liquid and the PAM dosing system 9 is controlled by a pump 10. The liquid is mixed in the pipeline, and under the action of PAM, the flocculation effect of the sludge is increased, which is beneficial to the sludge granul...
example 2
[0021] Example 2: Attached figure 2 The segmented return UASB unit shown - the cone set facilitates sludge granulation.
[0022] Two sections of reflux are set up, the reflux liquid intake point 8 of each section is set above the cone group 3 composed of three cone buckets, the reflux water inlet point 12 is set below the cone group, and the UASB reaction zone is divided into two large sections that do not interfere with each other. Part, each part has guaranteed the optimal condition that each section microorganism needs, and all the other are with example 1.
example 3
[0023] Example 3: Attached image 3 The mechanically agitated UBF-cone set-up shown facilitates sludge granulation.
[0024] The UBF effluent passes through the packing layer 14 for mud-water separation, and a mechanical stirring device 13 is added to the reactor as an external power, and two sets of two-cone bucket-cone groups 3 are set. Mechanical Stirring UBF- During the operation, the stirring intensity of the mechanical stirring device 13 at each height can be adjusted according to the actual situation, and the swirl intensity can be controlled by controlling the blade shape, size, and rotational speed. All the other are the same as example 1.
